Hayden Panettiere's Mom Lesley Vogel Says Hickerson Brothers' Account of Daughter's Death Is 'Full of Holes' — 'Brian Had to Go Out and Buy Narcan'

Hayden Panettiere's mother, Lesley Vogel, spoke out about the circumstances surrounding her daughter's death, saying the account given by Brian Hickerson is "full of holes," RadarOnline.com can reveal.

Vogel questioned the timeline of Hayden's final hours and, in particular, how Narcan came into Hickerson's possession.

In an exclusive hour-long interview with the Daily Mail, Vogel said she pressured South Carolina law enforcement to investigate Panettiere's death and told an officer at the scene that she believed Hickerson was "culpable."

Vogel said Hickerson told police that Hayden was doing her makeup at the Greenville Airbnb around 10:30 a.m. on Sunday, August 16, before he left to get something and later returned to take a nap.

According to Vogel, Hickerson's account to police did not include him seeing or speaking with Panettiere after he returned.

She said he later told officers that his brother Zach Hickerson knocked on the door, prompting Brian to answer, at which point Hayden was found unresponsive.

Lesely believes that version of events leaves important questions unanswered.

"I think there will be a discrepancy in the timeline," she told the outlet.

One of Lesley's biggest questions involves the Narcan that Zach said Brian administered to Hayden.

"Brian had to go out and buy the Narcan while he left her there because I do not believe he happened to have two bottles of Narcan on him, like he carried them around in his back pocket," Lesley claimed.

She also questioned Brian's account that he had been sleeping near Hayden when she became unresponsive.

"I don't know how you can take a nap near someone who's dying and not realize something's wrong," Lesley said. "How do you do that?"

Lesley also offered her own theory about what happened before Zach arrived at the Airbnb, while emphasizing that it was her opinion.

"When the EMTs came it was for a cardiac arrest. People in cardiac arrest aren't just lying still. They make noise," she said.

Lesley then laid out what she believes may have happened.

"I think Brian called his brother. My opinion. I think he knew she was deceased. Called his brother, and tried and built this story," Lesley speculated.

Brian has not been accused of any crime.

Lesley said she believes Brian and Hayden had a toxic "codependent bond" that became increasingly difficult for her family to break.

"When Brian came into her life, the changes started to occur," she said. "Very early in the game, I thought he's a modern-day gigolo. I know what he's after."

Lesley expressed that she is determined to remain strong while pursuing answers surrounding Hayden's death.

"There is infinite sadness," Lesley said. "But this is not the time for me to be weak. I don't have the luxury right now of being weak. I have too much to do for Hayden. When I'm done with that, then I will give myself the luxury to mourn - deeply mourn."

"I'm not saying I'm not grieving now. I am, and I do have my moments. But the bigger picture right now is I have to stay strong. I don't have an option," the grieving mother added.
